Part Number: THS4052
Other Parts Discussed in Thread: TINA-TI, OPA2810

Hello guys,

One of my customers is considering using THS4052 as a DAC output voltage follower for their new products.

For that, they want to measure output impedance of the device used as a voltage follower.

Could you tell me how to measure the output impedance in Tina-TI?

It is very helpful if you send me a sample of sample circuit TSC (Tina-TI) file.

Best regards,

Kazuya.

The closed loop output impedance depends on the circuit configuration.

Can you describe what you are trying to do.

1. Voltage or current output from DAC

2. desired signal swings and speed

3/ most DAC's are complementary out - are you ending up single ended?

The THS4052 is quite old, you might look at the OPA2810. - that is just a guess not knowing your design requirements.

Hello Kazuya,

I am closing this thread since you seem to have started another one. I will include a TINA file for testing Zout on the new thread.

Best,

Hasan Babiker
